.Be it known that 1, WILLIAM Gr mm, a citizenof the United States, residing at lVichita, in the county of Sedgwick and State of Kansas, have invented new and. usefullmprovements. in a Street Inchcator,

oi. which the following is a specification.

ih/iy present invention has reference toa strcetor station indicator for rolling stocln An object is the production of simple electrically operated means wlnchwill accur ately indicate the next \stopof theyehicle in which the ,device is arranged Adfurther. object. is the production of a. streeeor. station indicator which is electrically operated either from an overhead or third rail electric system, but which may be also operated by electric means arranged in i the coaches of railroad :train, and by which thesheet containing the names of the streets or stations will beaccurately wound or unwound to positively disclose through a suit able opening in the casing therefor, the name of thelnext' street orfstation at which the vehicle will stop. y

The foregoingyandmany other objects which will appear as the nature of tl1einventlonisbetter understood, may beaccomplished by a construction,combination and operative arrangement of parts, such as is illustrated by the drawings. it In; the drawings Figure 1 is a diagrammatic 1 view oi? a coach in whichthe controlxcircuit s actuated from an overhead conductor.

Figure 2 is similar view 111 which the control circuit is operated by the conductor of the third rail system;

Figure 3 is a viewshowing the arrangement of the indicatorin acoach.

Figure 4 is a fragmentary elevation trating the contact on the trolleyharp in engagement with one of the contact plates se-y cured to a guywire above the trolley wire.

tion illustrated in Figurefifl i i H v r 1 While in the; drawings 1 have illustrated the'control circuit operable from elements on the conductor of an overhead and the conductorof a third rail or underground rail It igure 7 is a side elevation of the construcway system, I desire it to be understoodthat,

contact members may be arranged at desired points on the track of a steamrailroad which vwill operate the control circuit, the said 011? cuit, in the latterinstanceincluding therein a source, of energy, snchas arbattery. ,Also. while the device hasbeen.illustratedas ar ranged in only one coach it Will be apparent thatthe indicator may be arranged 1n allot the coaches making up atrain. i 1 On the overhead conductor 1, :at points i 1 near a street or station; I secure on guy wires,

2 that-are mechanically connected with the conductor 1, depending contactplates 3.

On the harp of the trolley pole & I secure. laterally arranged upwardly extending circuitmakers 5. The circuit makers include each a fixed and a movable, preferably. spring contact, the latter being in tl1e1pathofen- 1 gagement with the plates 3 and the said contactsare connected to the wires 6 and 7. of thecontrol circuit. Between the conduc-:

tors- 6 and 7 there may be arranged a switch the numeral 14, and is influencedby'a spring 15 away fromthe cores of the said magnets. To the armature 14 is connectedwthe con ductor 13. The conductor 9-1eads to the Winding oi'the motor 16,"the return .wire,

indicated by the numeral 17Fhaving itsfend provided with a contact18 in the path of engagement withthe armaturel i. when the control circmt 1SCl0Sd.. r

\ stationsindicated on the said sheet.

Before proceeding further it is to be understood that theconductors for the operating or motor circuit are connected with any desired source of electric power, such source having not been deemed necessary to illustrate in the drawings.

The shaft of the motor 16 has secured thereon a pinion 19 which is in mesh with one of the pinions of a train of reduced pinions or gears 20. The shaft 21 -for the lower roller 22 of the indicator sheet 23 is connected with the reducing train 20 The sheet 23 is of non-electric conducting material and has its outer face imprinted with the spaced names of streets or crossings over which the vehicle passes. The sheet and the rollers therefor are encased in a suitable hOuSin Q/ l which on the outer face thereoli,

has a transparent sight opening 25 whereby only one of the streets or stations marked on the sheet will be displayed at a time. The upper roller for the sheet 23 is indicated by the numeral 26, and has its shaft 27 provided' on one end with a sprocket wheel 28. Onthe; shaft 21 is a similar sprocket wheel 29/ Around the sprocket wheels 28 and 29 there; is] loosely arranged an endless sprocket chainBO.

The sheet 23, at one of the edges thereof has spaced preferably rectangular openings 31 therethrough, the said openings being disposed opposite the' respective streets or On the outer face of the sheet in a line with the said openings 31 is a spring contact member 32. On the inner face of the sheet, opposite the contact member is a second spring contact member A conductor 34% loads ductor wire 37 that terminates in a contact 38 that is above and slightly to the rear of the contact 18 for the conductor 17 of the operating circuit 10. Below the magnet, but in the path o1 engagement therewith is a substantially'V-shaped catch 39 that is infi uenceel by a spring a0. Pivotally supported, off of its center there is a lever 7 5. The sprocket wheels 28 and 29 are loosely j ournaled on the shafts 27 and 21, the hubs of the said wheels being provided with clutch elements 28 and 29 respectively. Keyed for slidable movement on the shafts 27 and 21 thereare clutch members 76 and 77 respectively. The slidab'le clutch members are rounded in cross section, and are centrally provided: with grooves in which are received forksZS and 79 respectively on the lever 75. It will: be apparent that by shifting the lever eitherof the clutch memhers 76 or 77 will be brought to engage with the clutch faces 29 or 28. on the respective sprocket wheels 29 or 28. so that the shafts Q1 and 27 will turn to draw the sheet 25, oil oi one oi the rollers and on to the other roller to which the said sheet is secured. in this manner, the movement of the sheet will be reversed when the car has reached its terminal and is making its return trip.

.he operation may be briefly described as follows. The circuit makers 5 are closed by engagement with the plates 3, closing the control circuit which energizes the magnets 11 and causing the same to attract the armature 14:. The armature Ll first engages the contact 18 of the conductor 17 of the oper ating circuit 10 closing the same and operating the motor 10 which operates the rollers oil? the indicator. The reducing gears pcrn'iit oi the rollers being slowly turned. ln1niedi ately a ltcr the arn'iaturc engages the contact 18 to close the operating circuit loll. the same is engaged by the substantially V-shapcd catch 39, which influenced by its spring ll) will draw the said armature into engage ment with the contact 38 of the shunt circuit. lVhen this takes place, the contact fingers 33 and 32 of the shunt circuit will be brought into engagement with one of the openings in the sheet 23, causing the magnet 36 to be energized which attracts the catch 39 bringing the same out of engagement with the armature lt and permits the spring 15 to move the same away from the contact 38, thus dcenergizing both the operating and shunt circuits.

The operating and shunt circuits are similar in the application of the improvement to the underground or third rail electric system as well as the arrangement of the dcvice in the coaches of a steam railway.

In the third rail system, the conductor rail ll has a contact member 43 secured thereon which is in the path of engagement with a circuit maker 44 that is connected to one of the wires 46 of the control circuit. The second wire 47 of the control circuit is connected to the contact shoe 48 (ii the system.

It is thought that the :lorcgoing descrip tion, when taken in (fOllllQt'lIlOll with the drawings will fully set 'l'ortli the constrl.u-. tion and advantages ol the improvcnimit without further detail description.

In Figures (5 and 7, only one circuit maker 5 is connected to the trolley harp. The trolley pole, in the said figures is indicated by the numeral i, the guy wires by the numeral 2, the trollev wire or conductor by the numeral 1", and the conducting wires by the numerals 6' and 7. I

The rolls may be reversed at the terminals of the line by simply reversing the motor 16.

Having thus described the invention. what I claim, is I In a station indicator, rolls and shali'ts therefor an aperturcd sheet having the lIiU names of stations thereonseeurecl on the rolls for winding from one of the rolls on to the other roll, sprocket, Wheels loose on the shafts, a chain trained therearouncl, motor operated means for intermittently imparting motion to one of the shafts, electrically operated means engaging the apertures in the sheet for holding the sheet from movement except Whenthe motor is operated,
